Multiple open redirect vulnerabilities in the Suricata package before 1.0.6 for pfSense through 2.1.4 allow remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via (1) the referer parameter to suricata_rules_flowbits.php or (2) the returl parameter to suricata_select_alias.php.

pfSense is a free network firewall distribution. pfSense is based on the FreeBSD operating system with a custom kernel and other changes. During a security audit, multiple vulnerabilities were discovered in the pfSense packages for Snort and Suricata. These include Cross-site scripting (XSS) redirection issues.
